A CORPORATION OF NEW CARRIER FOR PNEUMATIC-TUBE APPARATUS.

Specification of Letters Patent.

Patented July 9, 1912.

Application fi1ed October 14, 1907. Serial No. 397,239.

To all whom it may concern:

Be it known that I, FRED R. TAISEY, of Lowell, in the county ofHiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Carriers for Pneumatic-Tube Apparatus, of whichthe following is a specification.

My invention relates to improvements in carriers for pneumatic despatchtube apparatus and its object is to simplify the construction of thesame and to permit of their being easily taken apart for repairs or thereplacing of parts.

In the accompanying drawings is illustrated a construction embodying myinvention in which:

Figure 1 is a central longitudinal sectional view of the carrier. Fig. 2is a section on line 2-2, Fig. 1, looking in the direction indicated bythe arrow. Fig. 3 is an enlarged sectional portion of Fig. 1. Fig. 4 isa perspective view of the inner shell of the carrier showing location ofthe controlling disk. Fig. 5 is an end eleva- 7 and 8 are detail viewsto be hereinafter described.

Like letters of reference refer to like parts throughout the severalviews.

Referring to the drawings ;-A and B represent respectively the outer andinner shells of the carrier and having the peripheral openings a and bthereinadapted to be rotatably thrown into and out of cooperation withrelation to each other to open or The shell B carries the buffer Csecured to its closed end by means of nut N and screws 12. The oppositeend of said shell B carries the internal projecting flange E part ofwhich forming the stops F and G (see Fig. 8). The outer shell A isinclosed at one end and entirely open at the other end and carriessecured to its inclosed end the buffer D held in posit-ion by the screwsm and nut M.

H is a disk having stamped therein the depression J carrying the holes Kthrough which are adapted to pass the screws m to secure the disk to theinclosed end of shell A. This disk is mounted Within the shell B withits outer edge against the inside of the flange E and when said disk issecured to the shell A prevents the longitudinal sepaation of the shellsbut permits the rotation of said shells with relation to each other.

bodying the same,

To limit the rotation of these shells A and B to secure the properregistry and nonregistry of the openings (0 and Z), there is provided astop L stamped on the disk H, this stop being adapted to rotate with theshell A and disk H in alinement with the flange E on the shell B toengage the stops F and G. Vith the parts in the relative positions shownin the figures, the stop L engages the stop G when the openings (0 andI) register and when these openings are closed the stop L engages withthe stop F. To separate the parts, the screws m are withdrawn from thenut M when the shells may be separated and the disk H removed from theshell B.

I do not limit myself to the use of a nut to secure the buffer to theouter shell, as a disk may be used which limits the rotation of the twoshells in the place of said nut.

Having thus described the nature of my invention and set forth aconstruction emwhat I claim as new and desire to secure by LettersPatent of the United States is:

1. In a carrier for pneumatic despatch tube apparatus, two cylindricaltelescoping members each closed at one end and carrying a bufferattached thereto and having corresponding peripheral openings adapted tocooperate upon the rotation of said members, an internal projectingflange located on the open end of the inner member and carrying stopsthereon, and a plate bearing against the inner'surface of said flange toprevent longitudinal separation of the members, said plate being securedto the closed end of the outer member and provided with a stop adapt-edto engage said stops to limit the rotation of said members to theopening and the closing of the openings therein.

2. In a carrier forpneumatic despatch tube apparatus, two cylindricaltelescoping members, the outer end of each member being closed 'andcarrying a buffer attached thefeto-said members rotatable one within theother each having a corresponding peripheral opening therein, saidopenings cooperative upon rotation of said members, an internal flangeon the open end of the inner member and cut away to form stops, a cupshaped disk or plate bearing against the inner surface of said flangeand mounted inside of said flange and projecting into the open end ofthe inner member and secured to the closed end of the outer member toprevent longitudinal separation or" said members, and a laterallyprojecting stop or projection on said plate in alinement With the stopson said flange and adapted to engage the same to limit the rotation ofthe members to the opening and closing of the openings therein.

3. In a carrier for pneumatic despatch tube apparatus, an inner and anouter shell having one end closed and a buffer secured thereto, aninternal flange located on the open end of the inner shell and a plateor disk bearingagainst the inner surface of said flange and locatedWithin said flange and secured to the closed end of the outer shell, andcarrying a laterally projecting stop adapted to cooperate With saidflange to prevent longitudinal separation of said shells and to limitthe rotation therein.

In testimony whereof, I have signed my name to this specification in thepresence of tWo subscribing Witnesses, this second day of October A. D.1907.
